I have had thrush for around 6mths now, after going on antibiotics for a sinus infection. Since then, I’ve been treated with a topical cream, an oral fluconazole, 2x6 day courses of pessaries and 3x oral fluconazoles, taken a week apart. Whilst, after treatment, the discharge and itchiness died down, the discharge has never fully disappeared and within a few days is noticeable again. Also, the itchiness begins to return after around a week.
